EMILACING PROCESS AND APPARATUS.

Application filed February 11. 1918.

To all whom it may conccrn:

lie it known that I. EDWIN L. VIEGAND, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio. have invented a certain new and useful Improvement in Emplaciug Processes and Apparatus, of which the following is a full. clear. and expet description, reference being had to the accompanying drawings.

This invention relates to apparatus for emplacing elements in bodies of supporting material; and has to do also with the process involved.

The invention is peculiarly adapted (but not necessarily limited) to the production of electrical heating devices, and is herein illustrated in such connection.

While the main object of my present invention is to improve the apparatus disclosed in Letters Patent No. 1,133,347, issued to me on March 30. 1915, and to render automatic certain phases of its operation, the present invention contemplates a broader field of use than that expressed by the pat ent above referred to. It may be said therefore to have as its general objects the provision of apparatus whereon an element may be quickly and conveniently given a definite form and by means of which it may be readily emplaced or embedded in a supporting body of impressionable or plastic material. the apparatus operating with ease and precision enabling products of a high grade to be manufactured rapidly and economically.

The invention further comprehends a process of emplacing an element in a body of impressionable or plastic supporting material in such manner as to cause the element to be effectually imprisoned therein and securely held against accidental displacement, as might otherwise occur by reason of the elements tending to resume its former shape if made, as usual, of resilient material.

The foregoing objects, and others which will become apparent as this description proceeds, are attained in the exemplifies.- tion of my invention illustrated in the drawings accompanying and forming a part hereof; and While I shall proceed to describe the present embodiment in detail, I wish to be understood as not limiting myself to the structural details thereof further than Specification of Letters Patent.

is required by the terms of the claims annexed hereto.

In the present embodiment, the bed 1 of the apparatus is incorporated in a table structure designated generally by the reference numeral 2. Ears 3, spaced laterally from each other, rise from one end of the bed and carry opposed ivot points 4, either or both of Which may e adpistable within its or their supporting ear or ears 3.

One end of an arm 5. is supported by and between the pivot points 4. and its opposite end is forked in the nature of a yoke, to receive between the opposed branches 6 and 7 thereof What I shall refer to generally as the head 10. This may also be regarded in a broad sense, as the carrier for the element to be received.

The head 10 is made up of a number of parts including a supporting ring 11 (see Figs. 4 and 5), and is sustained for oscillatory movement upon a horizontal axis by a stud 12 that is jourualed within the branch (1, and by the inner end 13 ot' a screw H that is threaded through the other branch 7, the screw 14 extending beyond the outer face of the branch and having applied to it a handle 15. WVashers 16 are shown as interposed between each branch and the adjacent face of thesupporting ring.

The inner end of a spiral spring 20 is fastened to the exposed portion of the 'stud 12, and the opposite end of the spring is anchored to a pin 21 that projects from the side of the branch 6. rearwardly of the spring. The extreme outer end of the stud 12 is provided with a wrench receiving portion 22. to facilitate screwing the stud into the supporting ring.

As will be seen presently, in the operation of the apparatus it is necesary to oscillate the supporting ring, first in one direction and then the other, through substantially 180 degrees. and in this connection it may be explained that the stud 12 is fixed with respect to the ring. The spring 20. being under tension and disposed as shown in Fig. 3. tends to rotate the supporting ring in a right hand direction. and the movement of the ring in this direction is arrested by the engagement of its stop 24 with a suitable cushion device, in the present instance the same constituting the plunger '25 of a dash-pot 26 that is supported within a web 27, disposed within the fork of the arm 5 adjacent to branch 6. The movement of the suporting ring in the opposite direction is arrested by the engagement of its stop 30 with the lower end of a stud 31 that is ad-- justable'within a web 32, located adjacent the branch 7.

To maintain the supporting ring 11 in either of its positions during certain phases of the work, and for reasons which will be brought out during the description of the operation of the apparatus, I provide a latch for cooperation with each of the stops 24 and 30. That for cooperation with the stop 30 consists of an angle lever 35 that is pivoted at. 36 tothe underneath side of the inner end of the branch 7. When the stop 30 bears against the stud 31, the latch end 37 of the lever 35 may be projected beneath an adjustable abutment 38, carried by the stop 30, by swinging the lever in the direction indicated by the arrow in Fig. 9, by means of the handle 39, (the disengaged position of the parts being indicated in said figure by dot and dash lines). It follows from what has been said above in regard to the spring 20, that when the lever is swung to disengaged position to release the stop 30, the

ring will be rotated by the'spring to engage its stop 24 with the plunger of the dash pot 2. Now by returning the lever 35 to its former or engaged position, it will, through the intervention of a link 40, swing a bell crank 41 upon its pivot 42 to project its latch end 43 over an adjustable abutment 44 that is carried by the lug 24. Thus it will be seen that the supporting ring may he latched in either of its ositions by means of this same general mec anism that is actuated by the handle 39. A

I shall now describe the organism of the head 10. W'ith tluuhead in position shown in Fig. 4. an annular member 50, which I shall term the turn-table surmounts the supporting ring. and to insure freedom of rotation of the turn-table upon the supporting ring I interpose between the two, antitriction bearings 51. The central bores of the supporting ring and turn-table are. of the same diameter and receive the cylindrical neck 53 of a turret 54. Inasmuch as the present apparatus is designed for use in the production of sad iron bases, the turret 54. and the parts which it supports. conform in outline to a sad iron base. Fillister head screws 55 extend through holes 56 in the turn-table and are threaded into alining tapped apertures 57 ot the turret. The adjacent faces of the turret and turn-table are recessed about the screws to receive springs 60. and cavities 61 are formed in the opposite side of the turn-table to accommodate the heads of the screws 5:"), the cavities being of suliicient depth to permit longitudinal movement of the screws without the heads striking the supporting ring. A cushion 62. which may consist of a washer of rubber, or other suitable material, is interposed between the supporting ring and turn-table to absorb the shock incident to the operation of the apparatus. As shown the heads of the screws engage the bottom walls of the cavities 1 to hold the turret and turn-table against undue separation; and the turret and turn-table are held in proper relation to the supporting ring by a retainer 64 that is connected, by screws, 65, to the end of the turret neck 53 and overhangs the inner edge of the supporting ring. A cap 66, attached by screws 67 to the supporting ring. incloses the retainer 64.

A post 70 extends through a longitudinal bore 71 of the turret neck and has attached to its end above the turret as viewed in Fig. a four branch cross-head 72 (see Fig. 11) that is reeiprocable within a recess 73 of similar shape in a plate 7-1. The

late 74 is secured to the turret by screws 5. A spring 76, within the counterbored upper end of the bore 71, and springs 77, occupying cavities TS'formed in the upper ima , head of a stud 83 is arra p fied smear the turret 54 beneath each'of the branches of the lcross-head 72, tend v to elevate the cross-head. This movement of the crossshead is controlled by means assowith each cam justabl and is held thereon by nuts 86. A handle 88 is aflixed to each end of the cross-arm. A- spiral spring 90 reposes within the cam ring 81' and is anchored atone end to a pin 91, by the arm, and at the other endfto a pin 92, carried by the cap 66. The spring 90 tends to rotate the arm upon the in a dlrection to cause theheads of the studs 83 to ride down the inclines of the cam rtions 82. a It will be observed, especiall m Fig. 7, that the am of each stud s3 is divided into two planes of difierent elevation' by 1i vertical lip 94, the cam engaging portion'95 to one si e of the lip being re erably inclined to correspond to the inc ination of th'e'cam portions 82. By rotating the cross arm 84 in 0 ition to the spring 90 until the Ii 94 0 5i: studs 83 snap over the ends of t e cam portions 84, the arm will beheld in its npwl assumed position; and it may be explain that, when in such position, the post and the cross-head 72 are retracted and springs 76 and 78 comp.

The form 100, whereon the element that is tobe received by the body of supporting material is given its shape is applied to the plates-74, and is rovided on its upper face with ribs 101. ising from the ribs are numerous element engatging projections 102, and the projections o the respective ribs are so disposed to those of the others as to impart to the element, designated E, the sh desired in any case, as that revealed in%g. 2. The form 100 is preferably made of steel with the ribs 101 int 1 with its bod portion and the projections 102 are produced by milling or otherwise cutting away the material between them and finishing each .PI'OJBGtiOll to present a comparatively sharp but smooth edge, as illustrated on an enlagfbd scale in Fig. 15, and about which the ement'ma betumed. By roducing the form in t is manner inste of by setting pins into a plate as in my former patent'hereinbefore referred"to, I am able to t the turns of the elementcloser toget er-as close, .in fact in the case of heat mg'devices, as safety against short circuitingpermits, resulti' in greater length and mass of element an consequently a longer life thereto.

The elements of electrical heating dc vices have terminals attached to their ends consisting of comparatively heavy wire.

These terminals I extend at right angles from the plane of the, element through bushin of suitable substance that are partially emfiadded in the body of supportm material. Preliminary to lacin the e emcnt upon the form, the terminal c is attached to one end, a bushin T'is applied to the terminal and insert into an orifice 105 in register with a bore 105 extending through the late 7-1 and turret, as indicated in dotted has in Fig. 8, and into which bore the p ll'ptruding end of the terminal roiccts. e element is then enga manna y or by mechanical means over t e projections 102 (Fig; 2) and justprior to applying it to the last few pro ections the element is cut to proper length, a terminal e is attached to its end, the remaining portion engaged over the remainder of the projections 102, a bush ing applied to the terminal 0' and the terminal with its bushing laced in the orifice 106 and alinin bore 1 entrance to which is facilitated y a slot or way 107 in the form and plate 74 and flanged end of the turret.

The turret is provided with a handle 110 for the purpose of turning it to and fro in a horizonta plane during the winding of the element upon the form. As will be more fully appreciated later on, it is essential to lock the turret in fixed relation to the supporting ring before the head is inverted for introducing the element into the body of supportin material. This is accomplished through t e locking pin illustrated in detail in Figs. 12 and 13. The pin 112 is shown as guided vertically within a bore in the supporting ring 11 and ca 66 and its lower tapered end 113 is adapts to enter a recess 114 in the turn-table 50 when the pin .is brought 'intoregister therewith and released. The reduced upper end of the pin extends through a bore in the cap (:6 which is counter bored to receive a spring 115 that tends to move the in into locking sition. A

.peg 116 exten s from the side 0 the locking pin throu h an L-shalfied slot 117 that opens through t 0 side of t e cap 66. By sping the head 118 and retracting the in and turning it so as to swin its peg 116 into the lateral branch of the s 0t 117, the lockln pin may he held in disengaged position whi e the turret is being swung as aforesaid in the element windin operation.

Nesting within and guardcd by l'lbS of the form I 00-is a stripper late 120, shown in perspective in 16. 1e stripper late is connected to the ends of the arms 0 the cross-head 72 by studs 121 which pass loosely through the apertures in the form, as shown best in Fig. 4. While the springs 76 and 77 act, through the croes head, to elevate the stripper plate, this action me be enhanced by auxiliary springs 123 w ich repose within registering recesses of the form and stripper late. Theremay beany desired number .these auxiliary springs disengage a section of the element dcsignated e in Fig. 2 and which extends along the form outside a set-in. rtion 101 of its rib, this or a similar construction being desix-able in the case of the particular, type shown, as will be readil unde The receivin element ,shown in dot and dash lines in g, 1, (which, in the present instance, constitutes a sad ironbas e that is partially filled with an impressionable or pllastic material, as set forth in my Patent 0. 1,133,347 previous] referred to) is supported upon a plate 12 applied to the forward end of the bed 1, and carrying suitable positioning devices 126 whereby the receiving-element is properly located with respect to the head. For the sake of simplicity and without limitin eifect, the receiving elements will be re erred to n certain of the claims as the base. a

The arm 5 is adapted to be sustained in elevated position by means of a lever 130, pivoted between the ears of a bracket 1-31 on the bed 1, the lever having a notch 132 in its forward edge for the recepfim of a pin 133 that is carried by the man. A spring 134- tends to rock the lever.-in the diredion of the pin and it may be conveniently swung in op head 135. U disengaging the lever from the pin 33, the arm 5 may lie-lowered more or lea forcibly to the dotted line'position of Fig. 1. From this dotted line position itmay be restored to its former position by few. power through the medium of mechanism which I shall now describe.

Pivoted upon a stud 139 suspended in .a bracket 140 from the under sideof the machine bedis a foot lever 141. Immediately to the rear of its fulcrum, the lever has pivwslly connected to it a rod 142 which rises through the bed of the apparatus and carries a fork 143 at its upper end which is normally sustained in a position to engage a pin 144, can'ic'd b the arm 5, when the arm descends. To

cess 114,

position to the springby means of its the heads of the dude Q3, thim rear extremity of the foot 5 lever is similarly connected a second rod 145 stripper plate remains in contact which rises through the bed 1 and has a fork 1416 applied to its u r end for the reception of a pin 147 that is carried to the arm .5, one branch of the fork being elongated to bear upon-the side of the pin and thus properly guide the fork as it a proadies the pin, when the arm is dep A compression spring 150 confined between the flange of a thimble 151 that is a plied to the rod 145 and bearing against underneath surface of the bed 1, and a collar 152 that is secured y a set screw 153 to the rod, keepsthe treadle mechanism .in the redzive psition shown in Fig. 1. It will'be-noted that the bed is slotted for the ge of the rod 145 to afl'ord the rod su cient swinging movement to follow the arcuate of the pin 147.

In the use of the machine, the operator,

startin with the parts in the 'tion shown in full mes in Fig. 1 and with the turret unlocked from the supporting rin windsthe element as already described. c then releases the locln'ng pin 112 and turns the tile rettobni thepm in mgisterwiflithem ring. The head 10 is then unlatchcd by swing ng the lever 35 outward; and, by grasping the handle 110, the operator invents the head and secures it in inverted sition' by returning the lever 35 to its ormer position. Byinverting the head, the tension of the spring 20 has been increasedf and the latching mechanism retains the head in inverted position the tension of. the-spring. The operator next d' the lever 130 from in 133, lowering the arm more or less forcibly as desired dependmg upon the consistency ofthe receiving mterial.

By impact of the head with the receiving element or base, the entering element is thorou'ghly embedded w'lhin the sup 'ng materm] and the material iseau to'ooze up about the element and into the d portions of the stripper plate the plate exerting a pressure upon the material and causing it to close in over and imprison the element in the manner already At the instant of impact, thereis a slight relative movement created between the parts normally maintained separated b the cushion springs 60,, suflicient to uni endsoflthecampoitionsofthenngfi 8 the stripper mechanism and allowing the spring 90' to swingathe cross-arm and the duds about over depressed of the cams (the swin ofjzhe crom ann being limited in both directions by the stops 155F-ig. 10). With the parts thus released, the springs 76, 77 and 123 elevate the form (and suimounting it) to withdraw the projections 102 from the base, while the crcby locking the W to the rawthe The operator may now depress the foot pedal 141, and the-initial movement thereof is transmitted to the arm through the rod 142. In point of connection of the rodfwith 5 the lever bein near its fulcrum, while the ,eng meat 0 the rod with the arm is'a materia distance from the pivot point of the arm, will cause the incipient upward move ment of the arm to be quite gradual so that the parts are gently removed from contact with the receiving element or base so as not to disturb the element, or in any way injure the poroduct. By thetime this has occurred, the rk 146 of the rod 145 has actively en- ,15 gaged the pin 147 of the arm and from now s the speed of the armwith relation to that of the foot lever isgreartly increased by. reason of the fact that the connection of the-rod 145 with the foot lever is quite rem'ote from the fulcrum of the lever while its connection with the arm is comparatively near the pivot of the arm. When the arm has attained its normal height, the lever 130 is swung forwardly by the spring 134 to en- 2 age the pin 133 within its notch 132 therer y'to hold the arm elevated. The operator may now retract the stripper plate and latch it in its normal position by rotating the cross-arm 86 to eng the lips of the studs 83 over the ends o t ihe cam. portions 82. Now by unlatching the head through the medium of the lever 35, the spring 20 will be permitted to return the head to normal or winding position, and upon the striking 'of the-lug 24 of the supporting against the stem of the dash pot 26, the lever 35 may be sw'un into engaging position to lock the head. y unlockin the turret from the supporting ring, t e apparatus will be placed in condition for a repetition .for the foregoing operation.
